How many weird terminal bugs do you have in your setup? Eg one that annoys me the most is that pressing esc in insert mode often takes a few seconds to do its thing.
any chance you have a key sequence mapping that starts with esc? sounds like its waiting to see if you are gonna be pressing another key before timing out and do its thing
